Biological process

up regulation of long-term neuronal synaptic plasticity, up-regulation of long-term neuronal synaptic plasticity, upregulation of long-term neuronal synaptic plasticity

A process that increases long-term neuronal synaptic plasticity, the ability of neuronal synapses to change long-term as circumstances require. Long-term neuronal synaptic plasticity generally involves increase or decrease in actual synapse numbers.

Note that the syntax of the definition of this term is different from the usual regulation syntax because it describes regulation of a trait rather than regulation of a process.
